HAY- ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 403,103, dated May 14, 1889.

Application filed February 13, 1889. Serial No. 299,807. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN L. HARKINSON, a citizen of the United States, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented a new and useful Improvement in Hay Elevators or Carriers, of which the following is a specification.

This invention relates to that class of hay elevators or carriers which are used in connection with a sling for raising the entire load of a wagon and conveying it into a barn or other suitable place of deposit; and it has for its object to provide a devicefof this class which shall be simple in construction and operation, durable, and inexpensive.

With these ends in view the invention consists in the improved construction and arrangement of operating parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side view of the car or carrier. Fig. 2 is an end View of the same. Fig. 3 is a perspective view illustratin g the arrangement of the car and operating-tackle, showing the device in operation.

The same letters refer to the sameparts in all the figures.

A A designate the side pieces or checks of the car, which are connected by means of,

bolts B B, forming bearings for the pulleys O D. The lower ends of the cheeks A A are provided with laterally-extending flanges E E and F F, through the former of which passes a bolt, G, upon which is journaled a small pulley, H, which is journaled between the said flanges. The flanges F F, being close together, form a lug through which passes a bolt, I, by means of which alink, J, is attached to the said lug.

Between the lower ends of the cheeks A A is inserted the upper end of ashank, K, which is firmly secured between the said checks by means of bolts L. The lower end of the shank K is provided on one side with flanges M, between which is hinged or pivoted ahook, N, Upon the opposite side the said shank is provided with a lug, O, to which a link, P, is at tached by means of a bolt, Q. The shankK is provided near its upper end with a recess, R, to receive the pointof a hook, N, which, when placed in the said recess, may be retained by means of a link or keeper, S, which is pivoted to the sides of the shank K by means of a transverse bolt, T. To the upper sides of the link S is attached an eye, U, for the attachment of an operating-cord.

The operating-tackle comprises a rope or cable, V, which passes overpulleys W and X, arranged, respectively, at the lower and upper ends of a pole or upright, Y, or which in practice may be suitably attached to the barn or other building into which the hay is to be conveyed. From the upper pulley X the ropeV passes over another pulley, Z, arranged at the upper end of a pole or upright, A, or in practice, probably, at the inner end of the barn or other structure, the car or carrier being supported upon the said rope V by its upper pulley D. After passing over the pulley Z, the rope or cable is returned and passes over the pulley O of the carrier, thence in a downward direction over a loose pulley, B, then through the link P of the carrier, and to the link J of the latter, to which it is firmly attached. To the block of the loose pulleys B is attached the hook C, the function of which is to en gage oneend of a hay-sling.

In operation the hay-slin g, which is denoted by letter D, is placed in the bottom of the wagon and the hay loaded on top thereof. When the wagon arrives at the place where the hay is to be unloaded, one end of the sling is connected to the hook N of the carrier, which latter is then secured in a raised or locked position by means of the keeper S, to the eye U of which the operating-cord E is attached, and passes over the pulley H, as shown in the drawings. The other end of the hay-sling is then attached to the hook O of the loose pulley B. Draft is then applied to the free end of the rope or cable V, which eX- tends from under the pulley WV, with the efiect of first tightening the sling around the load, and then raising or elevating the latter until it reaches the car. By the continued draft upon the free end of the cable the car then travels along said cable in the direction of the pulley Z until the place of deposit is reached, when the hook N is tripped by means of the operating-cord E, and the load is caused to dump. It will be seen that by simply changing the location of the pulley Z the load may be dumped ir any desired place.

This device is, as will be seen, exceedingly simple in construction, comprising only the carrier, the pulleys WV, X, Z, and B, and the single rope or tackle; hence it may be constructed at a small expense, and may be 0perated Without danger of getting out of order.

Special stress is laid on the particular conneci ion of the rope or cable V with the sling and carrier, whereby the sling is tightened When the draft is applied.

2. A carrier for hay-elevators, comprising the side pieces or checks, AA, the pulleys G D, journaled between the latter, the shank K, links J P, supporting-hook N, pivoted keeper S, pulley II, and trip-cord E, all combined and operating substantially as set forth.

3. In a hay-carrier, the combination of the herein-described car having pulleys C D, links J P, trip-hook N, keeper S, and pulley 0 H, with the rope V, pulleys W X Z, loose pulley B, having hook O, and the sling D, all. arranged and operating substantially as and for the purpose set forth.

In testimony that I claim the foregoing as 3 5 my own I have hereto affixed my signature in presence of two Witnesses.
